One or more epitaxial layers of compound semiconductor material such as GaN or InGaN is formed on the first growth substrate to create a portion of a vertical light emitting diode. Plural trenches are formed in the compound semiconductor material. Passivating material is deposited in one or more trenches. A hard material is at least partially deposited in the trenches and optionally on portions of the compound semiconductor material. The hard material has a hardness greater than the hardness of the compound semiconductor. A metal layer is deposited over the compound semiconductor material followed by metal planarization. A new host substrate is bonded to the metal layer and the first growth substrate is removed. Dicing is used to form individual LED devices.

Abstract: A method of making quasi-vertical light emitting devices includes growing semiconductor layers on a growth substrate and etching the semiconductor layers to produce device isolation trenches forming separable semiconductor devices and holes. Blind holes are drilled in the substrate at the location of each of the holes in the semiconductor layers. The drilling of the blind holes defines blind hole walls and a blind hole end in each of the blind holes. N-semiconductor metal is deposited in each of the blind holes. An n-electrode contact is formed in each of the blind holes by plating each of the blind holes with an n-electrode metal connected to the n-semiconductor metal. The substrate is thinned to expose the n-electrode metal as an n-electrode. Bonding metal is deposited to the n-electrode for packaging.
